Definitions

  • the present invention generally relates to an apparatus and method for shredding and crushing refuse and then baling the crushed material. More specifically, the present invention relates to a mobile apparatus that receives a high volume of material, such as tree branches, trash, demolition materials from a roll-off container, or the like, shreds and/or crushes the material into smaller debris, compresses the debris into a bale, and then wraps the bale with material to hold the bale together for transport and storage purposes.
  • the apparatus may be portable so that it can be moved from one site to another and allows for a variety of materials (i.e. wood, metal, plastic, etc.) to be shredded and baled together at one time without the need for separation or sorting of materials.
  • a shredder or crusher typically has rotating blades which shred and shear material as it is fed into the shredding apparatus, and the shredded material may then be collected in a receptacle that may be located underneath or in proximity to the shredder.
  • shredders are designed to handle a specific type of material, such as plastics, wood, or paper.
  • the object of a shredder is to reduce materials to a much smaller size for recycling or disposal, as shredded material occupies much less space than non-shredded, intact material.
  • a drawback to typical shredders is the fact that, although the material is reduced in size, the smaller, loose material is harder to collect and contain when transporting and/or disposing. Additionally, typical shredders tend to include a plurality of rotating cutting mechanisms as well as a screening apparatus to ensure that only small sized debris is released from the shredder; any larger sized debris may make additional passes through the shredding mechanism until it is shredded to a much reduced size. It would be advantageous to provide an apparatus that is simplified to a single shredding or cutting mechanism, and whereby the resulting size of the shredded debris need not be screened to a uniform size.
  • baling process itself serves to compact the material and reduce the size of space occupied by the garbage or recyclable material.
  • a baler is a piece of farm machinery used to compress a cut and raked crop (such as hay, cotton, straw, or silage) into compact bales that are easy to handle, transport, and store.
  • a cut and raked crop such as hay, cotton, straw, or silage
  • Several different types of balers are commonly used, each producing a different type of bale - rectangular or cylindrical, of various sizes, bound with twine, strapping, netting, or wire.
  • Industrial balers are also used in material recycling facilities, primarily for baling metal, plastic, or paper for transport.
  • baler in industrialized countries today is the large round baler. It produces cylinder-shaped "round” or “rolled” bales.
  • the design has a "thatched roof' effect that withstands weather well. Grass is rolled up inside the baler using rubberized belts, fixed rollers, or a combination of the two. When the bale reaches a predetermined size, either netting or twine is wrapped around it to hold its shape. The back of the baler swings open, and the bale is discharged.
  • the bales are complete at this stage, but they may also be wrapped in plastic sheeting by a bale wrapper, either to keep hay dry when stored outside or convert damp grass into silage.
  • baling was primarily used in connection with hay, cotton, straw, or other types of fibrous materials. It has been contemplated that baling other types of materials, such as dirt, mulch, and household garbage, for instance, would be beneficial, because those materials could be compressed into much smaller units that would occupy significantly smaller volumes than the loose materials that remain uncompressed.
  • baling dirt and mulch for example
  • One problem, however, with baling dirt and mulch is the difficulty in compressing that material to form into a bale, and then ensuring that the bale would remain intact, rather than simply falling apart.
  • Hay, cotton, and straw bales tend to remain intact after the baling operation has been completed, largely due to the length and fibrous nature of those materials. Dirt and mulch, which includes much smaller particulate, would simply crumble out of the sides of the bale during the baling process, and thus, balers for these types of materials have never been successfully manufactured and commercialized.
  • U.S. Patent No. 5,052,170 describes a shredder attachment for a round bale hay baler which will effectively shred corn stalks or stubble, milo stubble and the like and discharge the shredded stubble into a round bale hay baler which will form a bale of stubble which has been shredded which can be used for feed, bedding and the like.
  • U.S. Patent No. 6,491,245 describes a mobile shredding and material handling and feed system, preferably for use in the handling and shredding of paper and other office related feedstock.
  • An embodiment of the system on the input side utilizes an input hopper, a first conveyor, a feed aperture, and a second conveyor which moves excess feedstock away from the entry to the shredder feed aperture to avoid jamming the feed aperture.
  • An embodiment of the invention on the output side utilizes a compactor, preferably one or more augers, to compact the shredded material exiting the shredder, and moving said compacted shredded material to the discharge or system output.
  • An embodiment of this material handling and feed system also applies for balers.
  • U.S. Patent No. 6,499,931 describes a vehicle for collecting, sorting and reducing the volume of recyclable wastes and regular household and commercial garbage includes a large container with plural compartments mounted to the exterior of the vehicle includes a lifting mechanism for lifting the container to the top of the vehicle so that its contents can be dropped through chutes into plural bins. Between the chutes and the bins are crushers and shredders for reducing of volume of wastes deposited in the bins. Other wastes are placed in balers for baling.
  • U.S. Patent No. 6,820,542 describes an apparatus for compacting and baling leaves, grass clippings, sticks, pine straw and other debris on lawns, yards, or fields is provided.
  • the apparatus may have diagonal brushes to gather debris for processing though a crusher, a conveyor belt to transport the crushed debris, and a baler to compact and bale the debris.
  • the baler may compact the debris by rotating the debris in a continuous band, into which baling material may be inserted to bale the debris.
  • the debris may be gathered and feed into a crusher that deposits the crushed debris directly into the baler for compacting and baling.
  • the apparatus may gather the debris with brushes and feed it onto a conveyor mechanism 30 that then introduces it into a crusher.
  • the crushed debris may then be feed into a baling mechanism that compacts and bales the debris for easy removal and disposal.
  • the present invention may be connected to a prime mover or alternatively connected to a portable base with a motor for driving the device.
  • Document US2009/293426A1 discloses an apparatus and method of processing and transporting waste according the preamble of claim 1.
  • the shredders and balers of the prior art suffer from disadvantages such as only being able to shred and bale a particular type of material, the design of the shredding apparatus is more complicated and therefore more expensive, and/or the shredding and baling apparatus is only capable of small scale jobs (i.e. shredding and baling twigs and leaves while being pushed around a lawn).
  • the shredder-baler may be mounted on a trailer or flatbed whereby the shredded material may transported to the baler via conveyer, allowing for a portable system that can be scaled up or down in size and driven anywhere shredding and baling is needed.
  • One useful technique would be to drive a single shredder-baler to a demolition or disaster site for quick and efficient clean up. For example, rather than needing ten to twenty roll-off container trucks lined up to collect and contain debris and materials, a single shredder-baler may be driven onsite along with a flatbed truck to collect and stack the bales. Potentially, a single flatbed truck could hold 15-20 roll-off containers worth of baled debris.
  • Another useful technique would be to use the shredding and baling combination apparatus on a trash or refuse collecting truck in order to compress and bale household or commercial trash.
  • the trash workers could load trash directly into a hopper or feeder for the shredder for shredding and subsequent compression and baling.
  • the bale of trash could be stacked onto a flatbed of a truck, and additional bales could be stacked on top of one another in a compressed state, which means that such a truck could transport vastly larger quantities of trash than currently available methods allow.
  • the bales When the trash bales are delivered to a landfill, the bales could be neatly stacked, creating a much cleaner appearance, with the added benefit that the bales only occupy approximately 10% of the volume of uncompressed, loose trash and refuse. Thus, in this way, a landfill having a certain land area could contain as much as ten times the amount of trash dumped there in an uncompressed, loose manner as is typical of landfills in use today.
  • the instant shredding-baling apparatus in a preferred embodiment, includes a shredding apparatus operably connected to a baler via a conveyor.
  • the shredder includes an intake hopper with sidewalls for receiving and containing materials as they are fed into the shredder for shredding.
  • a rotatable drum with cutting teeth spirally arranged along the drum is preferably centered within a lower portion of the hopper for cutting through material as it is fed into the hooper.
  • Fixed cutting teeth are preferably arranged in a row or rows along each of the longitudinal sidewalls of the hopper, adjacent the cutting drum.
  • the cutting drum is preferably motor-driven and rotates at a speed sufficient to cut and reduce the material in size so that it may be compressed and baled by the baler.
  • the size of the shredded material need not be uniform or a specific dimension, provided the material can be successfully baled by the baler.
  • the shredder-baler of the present invention is preferably designed in an industrial size to handle high volumes of material.
  • the baler includes housing having a fixed portion and a movable portion (or “door”) pivoting upward and outward in relation to the fixed portion, wherein the door may pivot between an open and closed position.
  • a series of rollers are arranged about the periphery of the housing, on an inner portion thereof, in a generally circular configuration.
  • a series of large, flexible bands or belts are positioned within the housing, extending almost the entire width of the inside of the housing, and engage the rollers during the baling operation.
  • the apparatus includes a hopper for feeding material to be baled (“bale material”) into the baler, and specifically for feeding the bale material to the inside area of the housing between the belts.
  • rollers positioned on the fixed portion of the housing include three rollers that are driven by a hydraulic motor (either directly, or indirectly via a pulley mechanism), along with two adjustable rollers that are slidably mounted so that they may move inwardly or outwardly with respect to the housing for purposes of belt replacement.
  • the rollers preferably include a driven roller, six fixed rollers, together with a movable tensioner roller.
  • the tensioner roller is mounted on a mechanism that includes a pair of tracks extending outwardly from the door, so that the tensioner can move inwardly and outwardly along the tracks.
  • the tensioner roll is used to push against the belt inwardly during the baling operation to apply compression forces onto the outer side of the belt, which serves to compress the baling material into an extremely tight configuration, so that the bale can maintain its structural integrity after it has been wrapped and released from the baler.
  • the tensioner roll mechanism is driven inwardly and outwardly by a hydraulic piston.
  • a pair of rotating auger members are disposed within the housing toward the outer periphery thereof, and are used to catch and remove any errant chips or pieces of bale material that fall between the belts and the housing, in order to prevent any such chips or pieces from interfering with the mechanical components of the baler.
  • the chips are caught up in the rotating helical screw blade and transported to an exit port in the side of the housing where they are ejected therefrom.
  • the bale material is fed through the hopper, and the hydraulic motors drive the belts that are positioned on the rollers in the baling cavity of the housing.
  • the tensioner roller moves inwardly to apply a compressive force against the belt and the bale material disposed within the baling cavity.
  • a sensor apparatus monitors the bale size to determine when the bale is nearing and has reached its maximum capacity.
  • a wrap feeder begins to feed a wrap (preferably a strong netting material) around the bale through several revolutions under high tension, in order to hold the bale together.
  • the wrap material is cut or broken, and the door opens to release the bale from the baler. At this point, the operation may start over again in order to create the next bale.
  • FIG. 1-16 One preferred embodiment of a shredding-baling apparatus 100 is illustrated in Figures 1-16 .
  • the apparatus presented herein is capable of being attached to any number of platforms or frames.
  • the shredder-baler 100 may be mounted on a dedicated platform 101 that includes a wheel or multiple wheels, so that it may be towed like a trailer behind any large mobile vehicle or piece of equipment, such as a truck, tractor, or the like.
  • the shredder-baler 100 may also be mounted to the bed of a large flat-bed truck. Further, the shredder-baler 100 may be attached to or incorporated with another vehicle or piece of equipment such as a trash truck.
  • the shredder-baler 100 may be used by itself as a single unit, or in combination with other heavy equipment in many different configurations, as desired. It is contemplated that in a preferred embodiment, the shredder-baler 100 is industrial sized and capable of providing clean-up to construction sites, disaster sites, or any other area where high volume and high-throughput removal of debris is needed.
  • the shredder-baler 100 includes a shredding assembly 200 adjacent and operatively connected to a baling assembly 10, preferably with a conveyor means 300 to convey the shredded material to the baling assembly 10.
  • the shredding assembly 200 includes an intake hopper 202 for receiving the material that is to be shredded, and a shredding mechanism 201 for shredding the material as it is fed into the intake hopper 202. The shredded material may then fall on to the conveyor means 300 below where it is transported to the baling assembly 10.
  • the conveyor means 300 preferably terminates above a baler hopper 46 that feeds the shredded material into the baling assembly 10. Once the material has been baled, compressed, and wrapped, it may be released from the baling assembly 10.
  • the shredding assembly 200 of the present invention is efficient in both cost and operation due to the simplicity of the design.
  • the shredding assembly 200 consists of a rotatable shredding mechanism 201, such as a cutting drum 208, located within an intake hopper 202.
  • a rotatable shredding mechanism 201 such as a cutting drum 208
  • the bottom of the intake hopper 202 is preferably open so that the cutting drum 208 is freely exposed to the conveying mechanism 300. In this way, as the material becomes shredded, the debris may fall directly onto the conveyor 300 after being passed over the cutting drum 208.
  • the shredder assembly 200 includes an intake hopper 202 for receiving the material that is to be shredded.
  • the intake hopper 202 is designed to be top-loaded and is comprised of two opposed side walls 203, 204 that extend upwardly at a preferably obtuse angle, and a front 205 and rear 206 wall that each define an opening 207 for receiving a rotatable shredding mechanism 201.
  • the bottom of the intake hopper 202 is preferably open to allow the shredded material to fall directly onto the conveyor 300.
  • Each of the opposed side walls 203, 204 preferably include at least one row of fixed teeth 211, 212 mounted horizontally along the length of each side wall 203, 204, as best seen in Figs. 4 and 8 .
  • the fixed teeth 211, 212 are discussed in more detail below. It is to be understood that the intake hopper 202 is not limited to the embodiment described and may be any shape or dimension suitable to hold the material that is to be shredded.
  • the intake hopper 202 may be loaded by hand by tossing material or pieces of scrap into the hopper 202, or preferably by construction equipment such as a material handler or excavator claw attachment that can grab and lift large quantities of material into the intake hopper 202 at one time.
  • the shredding mechanism 201 is comprised of a cutting drum 208 rotatable along a rotational axis and oriented along a horizontal axis.
  • the cutting drum 208 is preferably positioned in the lower, central portion of the intake hopper 202, parallel between the two opposed side walls 203,204.
  • the diameter and length of the cutting drum 208 may be any suitable dimension depending upon the desired size of the shredding assembly 200.
  • the cutting drum 208 preferably comprises at least a support body 209 and a plurality of cutting teeth 210 carried on the outer portion of the drum 208 and preferably arranged in a spiral orientation along the outer surface.
  • a shredding mechanism is described in U.S. Pat. No. 7,980,278 of Labbe et al. incorporated herein by reference.
  • the resulting cut is more powerful.
  • a 2x4 piece of wood is placed in a shredding mechanism with cutting teeth arranged in parallel longitudinal rows, (as typically seen in shredders of the prior art), as the 2x4 comes in contact with the row of cutting teeth, it will be pushed along with the row of cutting teeth, following the rotation of the shredder or drum.
  • This type of arrangement results in a less efficient cut that may require additional cutting drums working together, or additional passes through the cutting drum as it rotates.
  • the 2x4 makes contact with each cutting tooth following one another in quick succession. Rather than traveling with a row of cutting teeth as the drum rotates, instead the wood is pushed against cutting tooth after cutting tooth consecutively, being pulverized as the drum rotates.
  • a plurality of protective collars or ribs may be mounted concentrically at spaced intervals along the outer surface of the cutting drum, with cutting teeth mounted between adjacent collars.
  • protective collars is described in U.S. Pat. No. 7,967,044 of Labbe et al. incorporated herein by reference.

  • a motor 213 drives rotation of the cutting drum 208 at a relatively slow speed.
  • a preferred range of speed may be 35-55 rpm, with a more preferable speed of 45 rpm for example; although, it is to be understood that the speed may be set at any desired or suitable rpm depending upon the use. Although a faster speed may be used, a slower speed may allow for a more powerful and efficient cutting as large quantities of mixed materials are dropped into the shredding assembly 200.
  • the power unit 402 may be designed such that if the cutting drum 208 becomes obstructed in any way, for example an object gets stuck or lodged in the drum 208 as it rotates, then the motor 213 may automatically counter-rotate the drum 208 in the opposite direction for a predetermined amount of time until the obstruction is removed and cutting may resume. Preferably, this process is automatically controlled by the power unit 402, negating the need for operator intervention.

  • An obstruction of the cutting drum 208 may be determined by an increase in pressure detected by the pressure sensor 401 on the hydraulic pump 400. For example, if the drum 208 is rotating counterclockwise as it shreds through material, and resulting debris gets lodged in the cutting mechanism 201 causing an obstruction, then the pressure in the hydraulic pump 400 may rise.
  • the motor 213 driving the drum 208 may automatically switch rotation of the drum 208 in a clockwise direction for the predetermined time interval (for example, 30 seconds) to allow for the obstruction to become dislodged.

  • Rollers (24,26,28,34) are situated between the frame members (18,20), and a baling cavity 52 is defined between the frame members (18,20), and the rollers extend about a periphery of the housing 12 in a generally circular configuration between the inner walls 22 of the frame members (18,20).
  • the outer wall 23 is spaced apart from the inner wall 22 on each frame member, creating a defined and enclosed space for various components, including hydraulic pistons 38 and components, pulleys 54, drive belts 56, and the like. This arrangement allows these components to be separated from the baling cavity 52, and further, to be isolated between the inner 22 and outer walls 23, which protects them from outside elements, including water, dust, dirt, and the like.
  • An additional benefit to this configuration is that sections of the outer wall 23 may be removed for repair and maintenance purposes.
  • rollers 24,26,28,34
  • some of the rollers are disposed in a fixed position with respect to the housing, and are rotationally driven by a hydraulic motor 58 (either directly, or are driven indirectly via a belt or chain drive mechanism). These rollers are referred to herein as “driven rollers” 24.

  • the fixed rollers 26 simply rotate in correspondence with the belt (40,42,44) that engages them, due to frictional engagement with the belt.
  • a third set of rollers 28 is adjustable with respect to the housing 12, so that they may slide inwardly toward a central portion of the housing 12, thus loosening the belt; or outwardly toward a perimeter thereof, thus tightening the belt, and these rollers are referred to herein as "adjustable rollers" 28.
  • the adjustable rollers 28 are actually fixed during the baling operation, so for operational purposes, the adjustable rollers 28 behave in the same manner as the fixed rollers 26.
  • the adjustable rollers 28 are mounted to a slide mechanism 30 that is received into slots 32 in the housing 12, as shown, so that the slide mechanism 30 may be moved between an operational position (creating higher tension on the engaged belt) and a maintenance position (relaxing tension on the engaged belt), and secured into either position.
  • a means for adjustment is provided on these adjustable rollers 28 for maintenance purposes, simply to facilitate removal and reattachment of the belts that engage those rollers 28 when maintenance needs to be performed.
  • a tensioner roll 34 is used to push the belt against the bale material during the baling operation.
  • the tensioner roll 34 is mounted onto a track 36, as shown, and a hydraulic motor is used to push the tensioner roll 34 inwardly along the track 36 and against the belt 40 from the outside of the belt 40 (from within the belt “loop") via a hydraulic piston 38, as shown, in order to apply significant compression forces to the bale material during the baling operation.
  • the tensioner roll 34 is not driven in a rotational manner in a preferred embodiment, but instead is simply forced against the belt inwardly as described above.
  • the track 36 includes a chain mechanism 39 that engages with a gear 41 that is disposed on the outer part of the tensioner roll 34 axis.
  • the gear 41 and chain 39 assembly ensure that both sides of the tensioner roll 34 remain evenly positioned between the tracks, which helps to keep uniform pressure against the belt and baling material. Additionally, this gear and chain mechanism helps to provide a smoothly shaped, symmetrical bale, rather than a lumpy, irregularly shaped bale. This same gear and chain mechanism may also be applied to and incorporated in the hinged portion 62 of the door 16, discussed below, in order to provide uniform compression on each side of the bale during a baling operation.
  • the rollers (24,26,28) may include a small notch on a side thereof, for expelling small bale material chips that become lodged between the circular side of the roller and the inner wall 22 of the housing 12.
  • the concept is that the chip, which is pinched between the side of the roller and the wall 22, will fall into the notch during rotation of the roller, and then fall out when that portion of the roller disengages from the belt during normal rotation. Then, the chip can be expelled from the housing by the auger mechanisms 60.
  • a series of large, flexible belts (40,42,44) are used to rotate, compress and form the bales from the bale material.
  • Each of these belts (40,42,44) engage and wrap around a specific set of rollers (24,26,28,34) within the inner walls 22 of the housing, so that the driven rollers 24 rotationally drive the belts, and the fixed rollers 26 and adjustable rollers 28 guide the belts.
  • the adjustable rollers 28 are moved into maintenance position, thus loosening and reducing tension on the belt to facilitate removal of the belt from the rollers.
  • the adjustable roller 28 is then moved back into its operational position, which may provide tension to the belt, and then the adjustable roller 28 is tightened and secured into that operational posture.
  • three separate belts are used within the baler.
  • One belt 40 extends around all of the rollers that are positioned on the door side of the housing ("door belt” 40).
  • the top roller 24 that engages the door belt 40 is driven directly by a hydraulic motor 58, which is mounted on the side of the housing 12.
  • the remaining rollers (26) on the door side of the housing that engage the door belt 40 are fixed rollers, with the exception of the tensioner roller 34.
  • the upper portion of the inner wall 22 of the housing on the door side includes a hinged portion 62 that allows the upper three rollers to move upwardly and downwardly in concert with one another.
  • a hydraulic piston 38 is disposed between the hinged portion 62 of the door housing 16 on the inner wall 22 and a fixed portion 64 of the door housing 16 on an inner wall 22, as shown.
  • the hydraulic piston 38 exerts a closing or compression force on the hinged portion 62 of the door housing 16, and during the baling operation, as the bale grows larger, the hinged portion 62 is forced upwardly by the increasing size of the bale.
  • This arrangement helps to provide compression forces to the bale material during the baling operation.
  • a pair of contact sensors (66,68) engage the hinged portion 62 of the housing to determine 1) when the bale is nearing maximum capacity but has not yet reached maximum capacity, and 2) when the bale has reached maximum capacity. The sensor system will be discussed in more detail herein below.
  • an upper belt 42 engages the rollers on the upper side of the housing 12, while a lower belt 44 engages the rollers on the lower side of the housing 12, as shown.
  • the upper belt 42 is rotated by a driven roller 24 having an axle that extends outwardly through the inner wall 22 of the housing 12, which engages a drive belt 56 attached to a hydraulic motor 58.
  • a belt tensioner 70 mounted on the outer portion of the inner wall 22, engages the drive belt 56 that runs between the hydraulic motor 58 and the driven roller 24, in order to maintain tension on the drive belt 56.

  • a belt tensioner 70 engages the drive belt 56 between the hydraulic motor 58 and the bottom driven roller 24, as shown.
  • the belts (40,42,44) are positioned so that they are each in close proximity to one another, such as in the lower portions of the baling cavity 52 (where the bale is formed within the housing 12), except for a gap between the door belt 40 and the upper belt 42.
  • This gap in the top of the baling cavity 52 is adjacent to the hopper 46, and allows baling material to be fed by the hopper 46, through the gap, and into the baling cavity 52.
  • This arrangement allows baling material to be fed into the baling cavity 52 without having significant amounts of the baling material fall through any small cracks or gaps between the belts in the lower portion of the housing.
  • a pair of hydraulically driven augers 60 are positioned in parallel relation to the rollers (24,26,28,34) within the belts (40,42,44), near an outer periphery of the inner walls 22 of the housing 12, as shown. These augers 60 are rotated and directly driven by hydraulic motors 58 during the baling operation.

  • a preliminary contact sensor 66 is attached to the housing on the door 16 adjacent to the hinged portion 62, and senses when the hinged portion 62 begins to "open,” or move upwardly and outwardly due to the size of the bale. This preliminary contact sensor 66 is used to tell the operator that the bale is nearing its maximum capacity, but has not yet reached maximum capacity.
  • a final contact sensor 68 is mounted above the hinged portion 62 of the housing 12 on the door 14, and provides an alert signal when the hinged portion 62 has extended outwardly far enough to indicate that the bale has reached its maximum capacity.

  • the computer is programmed to provide systematically increasing pressure on the belt 40 and baling material as the baling operation progresses, so that the maximum pressure is exerted by the tensioner roll toward the end of the baling cycle when the bale is reaching maximum capacity.
  • the computer controls the amount of pressure applied by the tensioner roll 34, and preferably provides intermittent, cyclical pressure, so that the tensioner roll applies high pressure, then backs off and releases some pressure, and then reapplies significant pressure, all in a continuous cycle.
  • These sensors are all operatively connected to a computer system, which not only displays the information gleaned from the sensors on a display for the operator's information, but also for use in triggering and controlling other actions by the baler (or baler components) during the baling operation.
  • the majority of the moving components of the baler 10 are driven by the hydraulic system, which includes hydraulic motors 58 for rotating the driven rollers 24, and hydraulic pistons 38 for opening and closing the door 16 and for providing compression forces to the tensioner roll 34 and the hinged portion 62 of the housing 12 on the door side 16.

  • a touch screen display is used as an interface between the operator and the shredder-baler apparatus 100, so that the operator can control and monitor many aspects of the operation.
  • the computer is used to monitor the signals from the various sensors, as described above. This information is preferably displayed on the display screen as information to the operator.
  • the computer is used to automate and control many aspects of the baling operation. For instance, when the computer receives a signal from the preliminary contact sensor 66, it activates an alert signal for the operator to let him or her know that the bale is nearing maximum capacity. The operator may then begin to maneuver a skid steer near where the bale may be released, thus increasing time efficiency for lifting and bale and carrying it to a flatbed for stacking. When the final sensor indicates that the bale has reached maximum capacity, the computer automatically actuates the wrap feeder 48, so that the wrap material begins feeding into the baling cavity 52 to wrap the bale prior to releasing the bale from the baler 10.
  • the computer also monitors the pressure forces on the bales, the operation of the hydraulic motors 58, the hydraulic distribution valve 78, the hydraulic low pressure sensing pump, the actuation and speed of the wrap feeder 48 (for tension), and other parameters and systems, to ensure proper and safe operation. Certain events or warning signals received by the computer from sensors may act as a trigger to shut down the shredding and baling operation for safety reasons, in order to prevent additional damage to the shredder-baler apparatus 100 or its components due to a malfunction or improper use.
  • touch screen is the preferred display and interface
  • other types of displays or controls may be used.

As the belts turn the bale material within the baling cavity 52, the wrap material is fed into the cavity, wrapping around the baling material in the process.
  • the wrap feeder 48 is directly driven by a hydraulic motor 58, and the computer controls the motor speed so that the wrap is fed into the baling cavity 52 at a slightly slower pace than the belts (40,42,44) that rotate the bale material.
  • the wrap material is under significant tension as it wraps around the bale material, providing additional compressive forces on the bale during the wrapping operation.
  • the computer stops the wrap feeder 48 from feeding any additional wrap material into the baling cavity 52, and the wrap material (preferably high-strength polymeric netting) simply snaps, and the bale wrap separates from the wrap material positioned within the wrap feeder 48.
